My notebook comes with I7-620QM. My problem is that the Intel Turbo Boost is not working.

It was working before I update to the latest BIOS.

How do I know this? the Intel Turbo Boost applet does not show any spike, even when i'm doing video conversion. Intel Processor ID Utility also gave me an Expected reading of 2.67 Ghz and Reported reading of 1.19Ghz.

I was trying to google this problem and downloaded an application call ThrottleStop. The funny thing is that after I ran this app, the Turbo Boost started working, Intel Processor ID Utility gave a Reported reading of 3.06Ghz (the max with 2 cores).

I rebooted and the Turbo Boost does not kicks in until I run the ThrottleStop.

It seems that when windows 7 boot, it forgot to turn on Turbo Boost or something like that.

Can anyone helpe there, thanks in advance.

Update, I found out that the turbo boost will only work when the battery is plug in. I usually work at home and plugged in, so I took out the battery so that it will last longer.
